f cellular alchemy." Whereas the ancient alchemists sought to transmute mundane metals into gold or silver, modern scientific wizards have found ways to convert human skin cells—the base metal—into induced pluripotent stem cell (iPS)—the modern biological equivalent of gold. These iPS cells are capable of growing into a variety of tissues, which could ultimately lead to the capacity to cure certain diseases with a patient's own cells.In a second cellular programming trick, scientists transformed mature cells in live mice from one specialized type to another. This bit of biological witchcraft flew in the face of years of results that suggested that cell development was a one-way street. It has provided much greater understanding into the nature of biological and chemical processes that enable cells to stably adopt a specialized role [link widoczny dla zalogowanych], and has opened the doors to the field that's now being called cellular programming. Both of these techniques potentially side stepp the political mine-field that surrounds human embryonic stem cells.Ten years ago, a team from the University of Wisconsin-Madison developed a technique to get human embryonic stems cells (hES) from human blastocysts. This [link widoczny dla zalogowanych], not terribly surprisingly [link widoczny dla zalogowanych], ignited a large debate over bioeyilai:
